A Prospective and Observational Cohort Study to Evaluate the Treatment Model and Medical Economics of Advanced Gastric Cancer Chemotherapy in Clinical Practice in China

This study has been completed.

Shen Lin, Peking University Identifier:
First received: October 28, 2011
Last updated: May 7, 2017
Last verified: May 2017

This is a multi-center, prospective and observational clinical study. Eligible patients will accept generalized chemotherapy according to the investigator's assessment. Information related to the treatment, including medication, disease condition, expenses, etc. will be periodically collected. Follow-up at 2-month intervals will be periodically performed to continually collect information about the disease progression, subsequent treatment and survival until death or completion of the study.

Recruited patients will fill out questionnaires about quality of life before initiation of treatment, at Cycle 3 and completion of first-line treatment.

Condition Intervention
Advanced Gastric Cancer
Drug: Clinical chemo-drugs

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Prospective and Observational Cohort Study to Evaluate the Treatment Model and Medical Economics of Advanced Gastric Cancer Chemotherapy in Clinical Practice in China

Further study details as provided by Peking University:

Primary Outcome Measures:
  • chemotherapy regimen [ Time Frame: 2 months ]
    To evaluate the treatment model (singel or doublet or triplet chemotherapy)of patients with advanced gastric cancer in China

Secondary Outcome Measures:
  • overall survival [ Time Frame: 2 months ]
    OS means that from the first dose of treatment drug to death or lost, the follow-up visit will be performed every 2 months till death or lost

  • quality of life [ Time Frame: 6 weeks ]
    To evaluate the quality of life before and after chemotherapy of Chinese patients in real clinical practice

  • treatment expense [ Time Frame: 2 months ]
    To evaluate the treatment expense of first-line treatment of Chinese patients with advanced gastric cancer in real clinical practice

Biospecimen Retention:   Samples With DNA
the tumor tissue samples were collected to do gene mutation analysis

Enrollment: 498
Study Start Date: November 2011
Study Completion Date: July 2016
Primary Completion Date: July 2016 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Eligible patients will accept generalized chemotherapy according to the investigator's assessment.
Drug: Clinical chemo-drugs

Clinical drugs will be selected by the investigator according to recommendations in Chinese and foreign guidelines and depending on clinical experience and the patient's individual conditions, including but not limited to the drugs listed below:

Platinum products: oxaliplatin, cisplatin Fluorouracil products: 5-fluorouracil, capecitabine, TS-1 Taxanes: paclitaxel, docetaxel


Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
patients with advanced gastric cancer

Inclusion Criteria:

  1. The patient has histologically confirmed locally-advanced or recurrent and/or metastatic gastric or esophagogastric junction adenocarcinoma, has missed the opportunity of surgical excision, making curative therapy impossible.
  2. The informed consent form is signed.
  3. A specimen of tumor tissue (puncture biopsy or surgical specimen) is available.
  4. ECOG performance status is 0, 1 or 2.
  5. The patient's general conditions and functions of important organs allow generalized chemotherapy according to the investigator's judgment
  6. The patient is aged≥18

Exclusion Criteria:

  1. The patient is known to be allergic to any study drug.
  2. The patient is recruited in other clinical study or is planned to participate into other clinical study.
  3. The patient has previously accepted chemotherapy against advanced or metastatic diseases (the patient may be recruited if the previous adjuvant therapy/neoadjuvant therapy was completed more than 6 months before inclusion).
